Higher prevalence of water pipe compared to cigarette smoking among medical students in Southeast Iran

Smoking of water pipe (WP) and cigarettes has recently turned into a major global health burden. The present study aimed at assessing WP and cigarette smoking among Zahedan University of Medical Sciences (ZUMS) students in Iran.

A cross-sectional survey was conducted on 500 students in ZUMS (182 males, 318 females). The subjects were selected through randomized cluster sampling. Morgan's chart was applied to calculate the sample size; 96.6% of the attendees completed a questionnaire designed to address the aims of the study.

The mean age of the subjects was 21.2 ± 2.4 years. WP and cigarette smoker rates were at 31.2% and 15.2%, respectively. The age of smoking initiation ranged between 15 and 20 years. Friends played crucial roles in triggering the smoking in both groups of WP and cigarette smokers (78% and 54%, respectively). The main reasons for WP and cigarette smoking were entertainment followed by curiosity. Furthermore, males used more cigarette (26.5 vs. 8.7%) and WP (50.6 vs. 20.4%) than females. Among father and mother smokers, respectively, 54.2% and 60% of children were also WP smokers (p = 0.001). Also, 21.9% and 60% of children smoking cigarettes had father and mother smokers, respectively (p = 0.05).

Tobacco use, especially for WP seems to be at alarming rates among medical students in Iran. It is highly recommended to control the progressive prevalence of WP smoking by governmental/academic preventive measures as educational and smoking cessation activities.
